Summary α-Interferon (IFN) is effective in the treatment of hairy-cell leukemia (HCL), but the treatment is sometimes over a long period. Biological changes such as the increase of tumorigenicity can occur rapidly in vivo as a result of beginning this treatment; an increase in c-Ki-ras oncogene expression has also been observed. In order to determine whether the findings observed in vitro would be duplicated in an in vivo system, we decided to analyze the Ki-ras RNA and protein levels in the lymphocytes of three HCL patients, compared with these levels in seven normal donors and one nontreated HCL patients. Ki-ras was not activated by IFN, at least not in lymphocytes. Therefore, the data suggest that the drug could be used for longterm therapy with relatively low risk to the patients.
